P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
OBD-II Trouble Code Technical Description
Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
The Powertrain Control Module (PCM) uses the Manifold Absolute Pressure Sensor (MAP) to monitor engine load. (NOTE: Some vehicles have a Barometric Pressure (BARO) sensor that is integral to the Mass Air Flow (MAF) sensor and do not have a MAP sensor. Other vehicles have a MAF/BARO and a redundant MAP sensor where the MAP sensor functions as a backup input in case of MAF failure.
The PCM supplies a 5 Volt reference signal to the MAP sensor. Usually the PCM also supplies a ground circuit to the MAP sensor as well. As the manifold pressure changes with load, the MAP sensor input informs the PCM. At idle the voltage should be 1 to 1.5 Volts and approximately 4.5 Volts at Wide Open Throttle (WOT). The PCM looks for any change in manifold pressure to be preceded by a change in engine load in the form of changes in throttle angle, engine speed, or Exhaust Gas Recirculation (EGR) flow. If the PCM doesn’t see any of these factors change while detecting a rapid change in MAP value, it will set a P0106.

Potential Symptoms
The following could be symptomatic of a P0106:

A P0106 could be caused by:
Possible Solutions
Using a scan tool, watch the MAP sensor value with the key on, engine off. Compare the BARO reading with the MAP reading. They should be roughly equal. The voltage for the MAP sensor should read approx. 4.5 volts. Now start the engine and look for a significant drop in the MAP sensor voltage indicating the MAP sensor is working.
If the MAP reading doesn’t change perform the following:
Other MAP sensor trouble codes include P0105, P0107, P0108 and P0109.

Having some check engine light issues and after reading about this on various sites it sounds like it can get costly and tricky.. There is a tsb where the throttle body sensor is replaced under warranty if under 120k miles….I think the it is sensor and or electrical related. I bought the truck new…
Ok I was randomly getting a p0106 code and p0004. I replaced the Map sensor,no change. I forgot to mention that my truck would randomly shut down on me saying service stabiltrack and reduced power.

I have 6 codes that stay the same. all the rest don’t stay after reset. codes are P0106,P0107,P0108,P0122,P1478, P1598. Had to replace converter and both O2 sensors. just tested bat. and alt. both test good. can’t find any vacuum leak. kind of lost. any input might help….
Okay, so let me explain the situation: My boyfriend’s truck is a 2004 Chevy Trailblazer EXT with a 6-cyclinder engine and a 4×4. The engine light would come and go so we didn’t think anything of it till we tried to run it through emissions and they failed it because the check engine light was on. …
I have had the 171 and 174 codes for about 3 months. I checked for vacuum leaks several times (none found), checked fuel pressure (OK), and cleaned the MAF. No luck. Now I get the 106 and 507 codes randomly, and the last time all 4 codes together. I have replaced the MAP and the MAF sensors with…
We change battery yesterday. It had dead cell in it. E new battery was the same voltage just slightly larger in size. The check engine light then came on. Upon having tested we were told the MAP sensor was bad. Replaced the sensor today. Unhooked the ground on the battery for more an thirty min…

"Delete Error Code Permanently, Disable DTC Error Code Function for p0106 in the ECU"
In extreme cases, we even have the option to permanently remove the specific DTC p0106 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.
Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p0106.
